This patch series adds a skeleton ARM Cortex M3 CPU model and updates the
"microbit" machine type to use it.

The Cortex M0 emulation is not complete.  This just lays the groundwork so we
can implement the missing ARMv6-M feature tests in target/arm/.

These patches cannot be merged until ARMv6-M feature tests have been fully
implemented.

Julia: it should now be possible for you to tackle the Cortex M0 emulation
tasks that have been discussed on the mailing list.
